Swing Check Valves

Fluidline Valves Co Private Limited offers Swing Check Valves. A Swing Check Valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow, or off the seat to allow forward flow. Design features: The body is designed for strength to meet operating conditions, and contoured to minimize erosion and resistance to flow. The disc is opened and sustained in open position by the Velocity pressure of the fluid and closed by the force of gravity. Seating load and resultant tightness is aided by back pressure in the line. The body seat-ring is seal-welded to the body avoiding leakage in the path between the seat ring and the body. The seating surfaces are ground and lapped.
